Detailed Description

The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are given by way of illustration and explanation only, not limitation.

As shown in fig. 1, the purifying apparatus provided by the present invention includes a housing 2 having an inner cavity 1, a wind wheel 3 and a purifying module 4, wherein, in an axial direction of the wind wheel 3, the inner cavity 1 includes an axial air inlet 6 formed on an end wall 5 of the housing 2, the wind wheel 3 is rotatably disposed in the inner cavity 1 to supply air into the inner cavity 1 through the axial air inlet 6, in a radial direction of the wind wheel 3, a radial air outlet 8 is formed on a side wall 7 of the housing 2 to enable air entering the inner cavity 1 to be radially discharged through the radial air outlet 8, and the purifying module 4 is disposed on the radial air outlet 8, so that, when the wind wheel 3 operates, air is supplied through the axial air inlet 6 and discharged from the radial air outlet 8 after passing through the purifying module 4, thereby forming an air purifying flow mode of axial air supply and radial air discharge based on the wind wheel.

In the technical scheme, the inner cavity 1 comprises an axial air inlet 6 formed on an end wall 5 of the housing 2, a radial air inlet 8 is formed on a side wall 7 of the housing 2, and the wind wheel 3 is arranged in the inner cavity 1 (for example, the wind wheel 3 can be arranged in the axial air inlet 6, or arranged in the inner cavity 1 and spaced from the axial air inlet 6), and the purification module 4 is arranged on the radial air outlet 8, so that when the wind wheel 3 is in operation, air in a space to be purified axially enters through the axial air inlet 6 under the action of the wind wheel 3, then the flow direction is changed, the air is purified by the purification module 4 and then is discharged into the space to be purified through the radial air outlet 8, and the axial air and the radial air outlet form a swirling flow around the purification device, and the swirling flow further adsorbs air in other areas in the space to be purified, so that the air in the space to be purified can sufficiently flow, and the purification effect is improved.

Further, in order to improve the effect of the axial air intake, preferably, the wind wheel 3 is located at the center of the inner cavity 1 and the central axis of the wind wheel 3 coincides with the central axis of the axial air intake 6, and preferably, the wind wheel 3 is disposed in the axial air intake 6, so that, under the action of the wind wheel 3, an intake air flow facing into the inner cavity 1 is formed at the axial air intake 6, and the intake air flow and the radially discharged air flow form a vortex together, thereby further adsorbing the air in other areas in the space to be purified.

Of course, in the purification apparatus of the present invention, the purification module 4 and the radial air outlet 8 may be arranged on a desired side of the casing 2, for example, only on one side of the casing 2, or, in order to further enhance the purification effect, preferably, as shown in fig. 1, the radial air outlet 8 and the purification module 4 are plural, for example, 3 as shown in fig. 1, and arranged around the wind wheel 3, so that the wind wheel 3 axially enters air and then radially exits air through the plural purification modules 4 and the radial air outlet 8 arranged around the wind wheel 3, thereby forming plural swirl flows as described above.

Further, the shapes of the purification module 4 and the radial air outlet 8 can be selected according to actual requirements, for example, as shown in fig. 1, the radial air outlet 8 is formed as a square opening, and the purification module 4 is a square purification module fitted in the square opening. Thus, in the structure shown in fig. 1, 3 purification modules 4 are arranged on 3 sides of the housing 2, and of course, 3 corresponding sides of the housing 2 are formed with the radial air outlets 8, so that three swirling flows as described above can be formed.

Alternatively, in order to reduce the volume of the purification apparatus and improve the continuity of the swirl flow in the circumferential direction, it is preferable that the radial air outlet 8 and the purification module 4 extend along the circumferential direction of the wind wheel 3, such as the radial air outlet 8 and the purification module 4 formed in an arc shape, so that the radial air outlet 8 can discharge the purified air in an arc shape, and it is easier to spread the purified air around.

Further, radial air outlet 8 forms to the annular mouth, and purification module 4 forms to annular purification module, and of course, annular purification module can be annular structure as an organic whole, also can be the annular structure that forms through the concatenation of multistage segmental arc. In this way, the purified air will be diffused all around in the circumferential direction, e.g. in the circumferential direction.

Of course, in the purifying apparatus of the present invention, the wind wheel 3 is rotated by the motor connected to the wind wheel 3.

In addition, the relationship between the housing 2 and the wind wheel 3 may have a plurality of structural forms, for example, in one structural form, the housing 2 is formed as a housing of the wind wheel 3, the wind wheel 3 is rotatably disposed on the housing 2 and can rotate under the driving of a motor connected with the wind wheel, that is, the housing 2 and the wind wheel 3 at this time constitute an independent fan device, and the purifying module 4 is disposed on the radial air outlet 8 to form an independent fan device capable of playing a purifying role.

Alternatively, in another case, the housing 2 with the inner cavity 1 is a separate housing, and a separate fan is provided, which comprises the wind wheel 3, in which case the fan may be arranged in the inner cavity 1 such that the wind wheel 3 is rotatably arranged in the inner cavity 1 to supply wind into the inner cavity 1 through the axial wind inlet 6, i.e. the housing 2 and the fan comprising the wind wheel 3 are two separate products, but the fan is assembled in the inner cavity 1 of the housing 2.

Of course, in the purification apparatus of the present invention, the purification module 4 may be a non-energized adsorption purification module, or, in order to improve the air purification effect, it is preferable that the purification apparatus includes a power supply 9 supplying power to the motor connected to the wind wheel 3 and the purification module 4, so that the purification module 4 is formed as an energized purification module, thereby improving the degradation capability of harmful or odor molecules, wherein the power supply 9 is provided on the housing 2 and at the side of the wind wheel 3. In this way, it is possible to avoid the power supply 9 being arranged on the end wall of the casing, which increases the axial dimension of the entire purification device, making full use of the radial space of the purification device.

Further, as shown in fig. 4, a light indicating tape 10 is provided on an outer surface of a side wall of the housing 2. For example, purifier installs behind the upper surface of the storing cavity of refrigerator, and light indicator area is towards the refrigerator door, and like this, after the user opened the door, light indicator area 10 can be in the illumination, can also show purifier's operating condition and purifying effect in real time, because light indicator area 10 sets up to showing purifying effect.

In addition, in the purification apparatus of the present invention, the purification module 4 may be any known electrified purification module.

Alternatively, in order to further enhance the purification effect, it is preferable that the purification module 4 is an electrified purification module and includes a first electrode 11, a second electrode 12 and a porous insulating medium 13, as shown in fig. 1, fig. 2 and fig. 3, wherein the first electrode 11 and the second electrode 12 are arranged at intervals, and the porous insulating medium 13 is arranged between the first electrode 11 and the second electrode 12.

Like this, because porous insulating medium arranges between first electrode 11 and second electrode 12 to be formed with porous, thereby porous can let first electrode 11 and second electrode 12 discharge and spread whole insulating medium surface, become even face discharge mode with the relatively concentrated line discharge mode among the prior art, both increased effective smell removal effect face, delayed the contact time of peculiar smell molecule with porous insulating medium again, promoted the promotion by a wide margin of removing smell purification performance.

Further, the first electrode 11 and the porous insulating medium 13 are disposed on the mounting frame 14 while maintaining a space, and the second electrode 12 is disposed on the side frame 15, then disposed on the mounting frame 14 while maintaining a space with the porous insulating medium 13, and finally mounted on the upper plate 16, thereby forming a purification module unit.

Of course, the first electrode 11, the second electrode 12 and the porous insulating medium 13 may also be directly installed in the radial air outlet.

In addition, the holes on the porous insulating medium can be counter bores or through holes, such as straight holes, for example, honeycomb-shaped through holes or holes capable of extending in a bending way, so that good air circulation is ensured, and the effects of odor removal and purification are further improved.

In order to further enhance the purification effect, it is preferable that a catalytic layer is formed on the surface of the porous insulating medium 13. Therefore, the porous insulating medium can further excite the catalyst layer while discharging to be fully distributed on the surface of the whole porous insulating medium, the surface of the whole porous insulating medium is changed into a discharging surface, the catalyst layer can directly catalyze and degrade peculiar smell and can indirectly generate active substances under the excitation of a high-voltage electric field to assist high-energy active substances generated by high-voltage discharging to thoroughly decompose the peculiar smell into harmless or tasteless small molecular substances, and the ozone inhibitor has the effects of inhibiting and decomposing ozone to a certain degree.

Of course, in the purification module 4, one of the first electrode 11 and the second electrode 12 is a high voltage electrode, and the other is a low voltage electrode. Further, the high voltage electrode may be a wire electrode or a mesh electrode, and may, for example, comprise at least one wire electrode. As shown in fig. 2 and 3, the wire electrode is made of a high temperature and corrosion resistant metal material, such as copper, molybdenum, tungsten, stainless steel or other metal alloys. Preferably a tungsten wire electrode, the diameter range of the metal wire can be 0.1-1mm; the low-voltage electrode may be a mesh-shaped porous electrode, such as shown in fig. 3, the porous shape of the porous electrode may be a square mesh, a honeycomb hole, or the like, the porous electrode may be a metal material, such as stainless steel, copper, molybdenum, or the like, and preferably a stainless steel mesh; the low-voltage electrode can be woven, punched and the like; the thickness of the net is 0.1-1mm, and the mesh number is 10-400 meshes.

In addition, the porous insulating medium can be made of ceramic, heat-resistant glass, quartz, organic films, silicon rubber, polytetrafluoroethylene and the like, and comprises one or a mixture of more of the materials; the thickness of the porous insulating medium may be in the range of 5-20 mm. Furthermore, the two electrodes and the porous insulating medium are kept at a proper distance, the distance is preferably in a range of 0.5-10mm, and the error range of the distance is in a range of 0.1-0.5 mm.

The catalytic layer may include a catalyst or be made of a material to which a catalyst component is added, and the catalyst may be composed of oxides of platinum, silver, titanium, zirconium, gold, or the like, or a mixture of these oxides.

In addition, as shown in fig. 5 and 6, the present aspect provides a refrigerator purging control method including: the working state of a compressor of the refrigerator is identified, the on-off ratio of an electrified purification module of the refrigerator and the operation and the stop of a wind wheel are controlled according to the working state of the compressor, air to be purified in a storage cavity of the refrigerator enters air axially along the axial direction of the wind wheel when the wind wheel operates, and air is discharged radially outwards after passing through the electrified purification module radially outwards in the radial direction of the wind wheel, wherein the on-off ratio is the ratio of the on-time to the off-time of the electrified purification module.

Further, in order to better control the operation of the electrified purification module and the wind wheel according to the working state of the compressor and improve the purification effect under different conditions, the electrified purification module and the wind wheel are preferably controlled independently. Of course, it should be understood herein that both the electrical purification module and the wind wheel can be implemented by the control unit of the refrigerator.

In addition, in order to more timely and accurately determine the operating state of the compressor, it is preferable that the control unit automatically identifies the on-time rate of the compressor in a unit time, and compares the identified on-time rate in the unit time with the on-time rate preset in the control unit to determine the operating state of the compressor, so that the on-time rate of the compressor can more intuitively determine the operating state of the compressor during the operation of the refrigerator.

It is understood that the predetermined on-time ratio may be a specific value, such as 50%, 60%, or 70%, or preferably, the predetermined on-time ratio is a range value, such as 50% to 70%. Thus, the compressor can be determined to be in a normal working state as long as the recognized on-time rate in the unit time falls within the range value.

For example, if the control unit determines that the identified on-time rate in the unit time meets the preset on-time rate, for example, falls within the range, the control unit determines that the compressor is in a normal working state. Further, it may be further determined whether the refrigerator is in a daytime operating state or a nighttime operating state, because the operation of the refrigerator is different between the daytime operating state and the nighttime operating state.

Further, whether the refrigerator is in a daytime working state or a nighttime working state can be detected through an infrared sensor on the refrigerator. In this way, the control unit can accurately determine the specific operating state based on the infrared sensor.

For example, the compressor is in a normal working state, for example, the refrigerator is in a daytime working state, because the frequency of opening the refrigerator by a user is high in the daytime, and when the refrigerator is opened, the inside of the refrigerator can be exchanged with outside air, so that the air effect inside the refrigerator is improved, the on-off ratio of the electrified purification module is less than or equal to 1, that is, the on-time of the electrified purification module is less than or equal to the off-time when the compressor is in the normal working state, so that more energy is saved.

Of course, preferably, in a daytime working state, in order to achieve a better purification effect, preferably, the wind wheel operates in advance of the electrified purification module for a preset time T1, so that the wind wheel can disturb the airflow in the refrigerator and ensure the uniformity of a wind field inside the refrigerator, and/or the wind wheel stops after delaying the preset time T2 than the electrified purification module, so that the wind wheel can uniformly blow purified air to all corners inside the refrigerator as much as possible, and the uniformity of air purification inside the refrigerator is achieved.

Of course, the preset times T1 and T2 can be selected according to requirements, for example, the preset time T1 is 3 to 10 minutes, the preset time T2 is 5 to 35 minutes, preferably, the preset time T1 is 5 minutes, and the preset time T2 is 30 minutes. Of course, it should be understood that the preset times T1 and T2 may be other values, and the present invention is not limited thereto.

For example, if the refrigerator is in a night working state, at night, the refrigerator door is not opened basically or the opening frequency is very low, at this moment, the air in the refrigerator is relatively fixed and cannot be ventilated through the opened refrigerator door and the outside in time, at this moment, the on-off ratio of the power-on purification module is greater than 1, that is, the on-off time of the power-on purification module is greater than the off time, so that better purification is realized, and the energy conservation and the energy consumption reduction can be realized when the wind wheel stops.

If the identified on-time rate in unit time is not consistent with the preset on-time rate, for example, the on-time rate in unit time is far lower than the preset on-time rate, the compressor is judged to be in an abnormal working state, for example, when the on-time rate in unit time is larger than the preset on-time rate, the refrigerator is in a busy refrigeration operation, at the moment, the air in the refrigerator is poor, the on-off ratio of the electrified purification module is larger than 1, and the wind wheel and the electrified purification module synchronously operate, so that the on-time of the electrified purification module is larger than the off-time, and the wind wheel synchronously operates, and a better and more comprehensive purification effect is realized;

and when the recognized on-time rate in unit time is less than half of the preset on-time rate, for example, the on-time rate in unit time is far less than the preset on-time rate or the compressor is not started, the power-on purification module and the wind wheel are stopped, so that energy is saved and energy consumption is reduced.

Further, as shown in fig. 6, a control unit such as a microprocessor automatically recognizes the on-time rate of the compressor per unit time and controls the on-off ratio of the electrified purification module by intermittently controlling the switch according to the on-time rate, so that the electrified purification module can be installed to operate at a desired on-off ratio.

In addition, according to the refrigerator purification control method, when the refrigerator door is opened, the wind wheel can stop working, such as immediately stopping working, and the power-on purification module can stop working, such as immediately stopping working or not stopping working, according to the opening time of the refrigerator door, so that air in the refrigerator and outside air can be naturally exchanged, and energy consumption is reduced; and/or, when the voltage of the refrigerator is abnormal, the electrified purification module stops working to be in a self-protection state, and the wind wheel stops after delaying the preset time T3 so as to convey purified air to all corners in the refrigerator, so that the uniformity of air purification in the refrigerator is realized. Preferably, the preset time T3 is 5 to 35 minutes, and preferably, the preset time T3 is 30 minutes. Of course, it should be understood that the preset time T3 may be other values, and the invention is not limited thereto.

Finally, the invention provides a refrigerator, wherein the purifying device is arranged in a storage chamber of the refrigerator; alternatively, the refrigerator can implement any of the above described refrigerator purging control methods. Therefore, the production cost of the refrigerator is obviously reduced, and the refrigerator has an efficient air purification effect, so that the overall quality of the refrigerator is obviously improved.

The preferred embodiments of the present invention have been described in detail with reference to the accompanying drawings, however, the present invention is not limited to the specific details of the above embodiments, and various simple modifications can be made to the technical solution of the present invention within the technical idea of the present invention, and these simple modifications are within the protective scope of the present invention.

It should be noted that the various features described in the above embodiments may be combined in any suitable manner without departing from the scope of the invention. The invention is not described in detail in order to avoid unnecessary repetition.

In addition, any combination of the various embodiments of the present invention is also possible, and the same should be considered as the disclosure of the present invention as long as it does not depart from the spirit of the present invention.
